[0019] The utility model provides a pull-wheel steering device for a reverse-riding tricycle, comprising a body 1, a compartment 2, an adjustment mechanism and a protective shell 3, the adjustment mechanism comprising a handle 4, a connector 5, a rotating rod 6, a triangular plate 7, a fixed shell 16, two round rods 8, two wheels 9 and two adjustment assemblies, each of the adjustment assemblies comprising a fixed block 10, a connecting plate 11, two rotating columns 12 and two connecting rods, the connecting rods comprising a connecting rod body 13 and a collar 14. The above-mentioned solution solves the problem that the front box of the existing reverse-riding tricycles on the market is located above the front wheel axle, the center of gravity is high, and there is a risk of tipping when carrying people or goods.
[0020] According to this specific embodiment, the carriage 2 is fixedly connected to the vehicle body 1 and is located at the front end of the vehicle body 1. The fixed shell 16 is fixedly connected to the vehicle body 1 and is located between the carriage 2 and the vehicle body 1. The rotating rod 6 is rotatably connected to the fixed shell 16 and is located inside the rotating shell. One end of the connecting member 5 is fixedly connected to the handle 4, and the other end of the connecting member 5 is fixedly connected to the rotating rod 6 and is located above the rotating rod 6. The triangular plate 7 is fixedly connected to the rotating rod 6 and is located below the rotating rod 6. The two round rods 8 are rotatably connected to the triangular plate 7 and are respectively arranged at the two ends of the triangular plate 7. The two wheels 9 are respectively arranged at the two ends of the carriage 2, and the two adjustment assemblies are respectively arranged on the carriage 2.
[0021] By rotating the handle 4 between the handles 4 and the corresponding wheels 9, the connecting rod rotates accordingly, and the connecting rod drives the triangular plate 7 to rotate, so that the round rods 8 on both sides move in opposite directions. One of the round rods 8 pushes the adjusting assembly, and the round rod 8 on the other side pulls the adjusting assembly, so that the wheels 9 on both sides rotate in the same direction, which improves practicality. At the same time, under the fixation of the adjusting assembly, the axis of the wheel 9 is higher than the bottom wall of the carriage 2, which improves the stability of the utility model and reduces the probability of rollover.
[0022] Among them, the connecting plate 11 is set in an L shape, one end of the connecting plate 11 is rotatably connected to the round rod 8 and is located above the round rod 8, the fixed block 10 is fixedly connected to the connecting plate 11 and is located on one side of the connecting plate 11, the two rotating columns 12 are fixedly connected to the fixed block 10 and are located at both ends of the fixed block 10, one end of the two connecting rods is fixedly connected to the carriage 2, and the other end of the two connecting rods is rotatably connected to the corresponding rotating columns 12, the fixed block 10 is fixedly connected to the wheel 9, the round rod 8 pushes the connecting plate 11 to rotate, the connecting plate 11 drives the fixed block 10 to rotate, the two rotating columns 12 are clamped at one end of the connecting rod, and the fixed block 10 drives the wheel 9 to rotate, so that the wheel 9 forms an angle with the vehicle body 1 to achieve the steering purpose.
[0023] Secondly, the connecting rod body 13 is fixed to the carriage 2, the collar 14 is rotatably connected to the rotating column 12, and is sleeved above the rotating column 12. The collar 14 fixes the fixed block 10. When the round rod 8 pushes the connecting plate 11, the fixed block 10 can only rotate along the axis of the rotating column 12, thereby improving stability.
[0024] Then, a limit block 15 is provided at the end of the rotating column 12 . The limit block 15 contacts the collar 14 . The limit block 15 limits the position of the collar 14 to prevent the collar 14 from separating from the rotating column 12 .
[0025] In addition, the pulling wheel steering device for the reverse riding tricycle also includes two protective shells 3, which are fixedly connected to the corresponding wheels 9 and are respectively located above the corresponding wheels 9. The protective shells 3 prevent the mud or rainwater on the wheels 9 from splashing when the wheels 9 rotate, and at the same time prevent the wheels 9 from scratching against the carriage 2 when the wheels 9 rotate.
[0026] When using the present invention, the handle 4 is rotated, and the connecting rod body 13 rotates accordingly. The connecting rod body 13 drives the triangular plate 7 to rotate, so that the round rods 8 on both sides move in opposite directions. The round rods 8 push the connecting plate 11 to rotate, and the connecting plate 11 drives the fixed block 10 to rotate. The two rotating columns 12 are clamped at one end of the connecting rod body 13, and the fixed block 10 drives the wheel 9 to rotate, so that the wheel 9 forms an angle with the vehicle body 1 to achieve the purpose of steering. At the same time, under the fixation of the connecting rod body, the axis of the wheel 9 is higher than the bottom wall of the vehicle compartment 2, which improves the stability of the present invention and reduces the probability of rollover.
